Title: A bi-directional multi-frequency ripple control system
Inventor: FOORD PETER MAXWELL
IPC: G05F1/66
Filed: 1985-04-16
Granted: 1987-12-23
Abstract: The circuit comprises a transmitter (20) transmitting a code for reception by receiver, the transmission taking place by the coded signal being superimposed on the power frequency waveform as a sequence of waveform distortion.  A transmitter control unit (29) generates closely spaced frequencies in the transmitter, to enable the use of multi-frequency codes.  The receiver has a pair of synchronous filters driven  ninety degrees out-of-phase with each other with discriminating circuitry for squaring and summing the filter outputs to form a non-phase-sensitive output. The differences between the synchronous filter centre frequency and the incoming signal frequency are detected and used to give complete rejection characteristics, thereby producing a very narrow bandpass filter for the receiver detection system.

Title: Double sheet detection method and apparatus of sheet-fed rotary press
Inventor: WATANABE HIDEO
IPC: B65H7/14
Filed: 1985-03-21
Granted: 1988-12-01
Abstract: A theoretical reference value (L) is used set as a difference between an intermediate value (M) between a first theoretical amount of light transmitted through one sheet (Line A) and a second theoretical amount of light transmitted through two sheets (Line B) and the first theoretical amount of light (Line A). The theoretical reference value is stored in correspondence with the amount of light transmitted through a sheet. As the sheets pass through the detector, a difference is calculated between an amount of light transmitted through an nth sheet and an amount of light transmitted through an (n+1)th sheet. The theoretical reference value which corresponds to the amount of light transmitted through the nth sheet and which is defined as an actual reference value is read out.  The difference calculated when actual printing is performed is compared with the actual reference value.  Double sheet detection is performed in accordance with a comparison result.

Abstract: A position measuring instrument comprising a graduation unit and a scanning unit. The graduation unit comprises a centering flange, a graduation carrier and a measuring graduation located on the graduation carrier. The scanning unit comprises a scanning component which comprises a scanning graduation and a stop. During assembly, the scanning unit is positioned radially with respect to the graduation carrier by positioning the stop against the centering flange. The scanning component may then be moved along a guide towards the measuring graduation. As the scanning component is moved towards the measuring graduation the stop no longer contacts the centering flange. A spacing foil removably sandwiched between the measuring graduation and the scanning graduation is used to position the scanning graduation at a predetermined distance from the measuring graduation. A locking means is then used to prevent further movement of the scanning component along the guide.
